Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Dichloro-3,4,5,6-Tetrafluorobenzene.
1,2-Dichloro-3,4,5,6-Tetrafluorobenzene (CAS 1198-59-0), molecular formula C6Cl2F4 and molecular weight 218.96 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Dichloro-3,4,5,6-Tetrafluorobenzene (C6Cl2F4) is characterized by fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
